Details of the c1542 OBD Code
C1542 indicates a fault with the brake pedal switch circuit.
OBD code C1542 means Steering Angle Sensor Internal.
This code is triggered by the Electronic Stability Control (ESC) module when it detects a fault with the steering angle sensor’s internal circuitry.
The steering angle sensor is a critical component of the ESC system, providing information about the steering wheel angle to help the system determine the vehicle’s intended direction.
When the sensor’s internal circuitry malfunctions or fails, the ESC module sets code C1542 to indicate the issue.
Mechanic’s Tech Notes
Code C1542 indicates an issue with the brake pedal switch circuit in the vehicle’s electronic stability control system.
OBDII code C1542 typically indicates a problem with the transmission control module (TCM) power supply.
To diagnose, use a multimeter to check TCM power and ground connections for proper voltage levels.
Additionally, utilize a scan tool to confirm TCM communication over the Controller Area Network (CAN) network.
If the TCM is unresponsive, reprogramming or reflashing may be necessary.
Visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
This thorough inspection will help pinpoint the issue and guide you towards an effective repair.
